Mazak 5 axis slight post issues?

[bassn_07]

I'm still new to the machine and Mastercam and I;m having slight issues with the post. The post I'm using is pretty much dialed in except for one minor flaw. I'll do my best to explain...sometimes when I'm working with the trunnion at 90 degrees at the end of my operation my X and Y wants to move first, which is dangerous at times if my A axis needs to index. I would like for the tool to go home after every operation or at least on every A or C move.Is this something that could be dialed in on the post or possible am I doing something wrong? Here a sample of the code I'm getting.

This is what my ptlchg$ looks like

 

code:

---

ptlchg$          #Tool change

pcuttype

toolchng = one

toolcount = toolcount + 1

if toolcountn <= tooltotal, nexttool = rbuf(4,toolcountn)

else, nexttool = first_tool$

if wcstype = one, #Work coordinate system

[

pfbld, n$, "G28", "X0.", "Y0.", "Z0.", e$

pfbld, n$, "G92", *xh$, *yh$, *zh$, e$

]

if mi10$=one, n$, *sm00, e$

if mi10$=zero & mi4$ <> 1, pbld, n$, *sm01, e$

if mi4$=one, pbld n$, *sm00, "(CHECK BORE)", e$

ptlchg_com

This gives me on my horizontal (but only 4 axis) a complete return to home for each tool change. What does yours look like?

Sorry it took so long to get back to this but I must have overlooked it.

 

I couldn't even begin to tell you how my post looks because I don't know how to access it. How would I access the internal information of the post processor? Also, what would be the best way to learn how to edit the post...trial and error?

Any editor will open the .pst file. The .psb file is encrypted and you can look at it. This is to protect the work of those who made the post.

 

I have been messing with posts over 5 years and learn stuff all the time about them. This forum is a great resource. Do a search when you are looking to do something. I have made me a big old notebook and have several smaller notebooks from stuff I got off the forum, from other people, from the Internet, copied from books, and just trying things to see if they work. Necessity is the mother of all invention. Not needing to go to the dealer everytime for a post mod is a nice thing.
